Engineer’s Toolkit Link


Engineers today use speadsheets and programs for even the most simple tasks. Most  “packs” for calculations have a cost not affordable by independent professionals or small companies. Find here free and accessible cost alternatives.

What is available here are

As in the spreadsheet page, material was downloaded and made available here or have a link to other sites, respecting the instructions of the authors.

QBLADE is an open source wind turbine calculation software, integrated into XFOIL (airfoil design and analysis tool). This integration allows the design of custom airfoils and  calculation of their polars, extrapolation of polar data to a range of 360° and directly integration in a wind turbine rotor-simulation. This precious tool for wind turbine engineers is made available by courtesy of the Chair of Fluid Dynamics, Institute of Fluid Dynamics and Technical Acoustics of the Technical University of Berlin ( TU Berlin). 


Freeware program for plotting Cartesian, Polar and Cylindrical functions. Plots 2D and 3D functions and has many additional tools.

Atlas for Windows

Freeware program for plotting beam moment and shear diagram.


Very small, DOS based program, that calculates Mach number, true air speed, equivalent air speed or calibrated air speed when one of these speeds is given. Structures engineers sometimes have interface with flight tests. This simple program can be precious. The program opens a window when you double click on it and gives all instructions for use. 3

It can be downloaded and used completely free of charge for any purpose. It is an open-source office software suite for spreadsheets, word processing, presentations, graphics, databases and more. Available in many languages and works on all common computers. It stores all your data in an international open standard format and can read and write files from other common office software packages.

LISA 7.4.0

LISA is a finite element analysis package with modeler, solver and post-processor. It is free to download and use up to 1300 nodes. This limit can be removed with a license of a really affordable price. The types of analysis that can be done are Static, Thermal, Modal vibration, Dynamic Response, Fluid, Buckling,  Acoustic and Electromagnetic & electric.
